This procedure is for anyone who has a Prusa Mk3 and a SmartPad klipper control device.

1. Please read the procedure first¶

You are responsible for all operations carried out on your equipment. This procedure explains how to set up klipper on your printer. It has been tested and is fully functional. This procedure has been tested and approved for prusa mk3. Do not install it on other printers.

5. Firmware flash¶

Return to MobaXterm. Connect the printer to the pad and run the command:

ls /dev/serial/by-id*

You should have a device.

Run the following command to flash the printer:

make flash FLASH_DEVICE=/dev/serial/by-id/xxxxxxxxxxxxxx

XXXXXX corexponds to the one you obtained with the command ls /dev/serial/by-id*. For example: make flash FLASH_DEVICE=/dev/serial/by-id/usb-Prusa_Research__prusa3d.com__Original_Prusa_i3_MK3_CZPX0123X004XK05843-if00

6. Download configuration files¶

You can download the Prusa configuration file from the following link:

Printer.cfg: https://github.com/Yumi-Lab/yumi-wiki/blob/main/Klipper/Prusa/Mk3/printer.cfg

7. Mainsail Web interface¶

You can connect to your Mainsail interface from a web browser with the address http://Your IP address.

Example: http://192.168.1.74

You should arrive on this page. The error is normal. We haven't finished the configuration.

From the Mainsail interface, go to Machine (wrench icon) Click on the button to load files

Select configuration file and click Open. Your file will be uploaded to Mainsail.

Restart the Pad and connect the printer to it with the correct USB cable.

From the Dashboard, you should be able to control your printer.

8. Changer les paramètres de votre slicer¶

9. CURA¶

From cura, go to Preference/Configure Cura... In the new window, go to Printers and choose your X2 profile. Click on Machine settings

In the Start Gcode section put:

START_PRINT BED_TEMP={material_bed_temperature_layer_0} EXTRUDER_TEMP={material_print_temperature_layer_0}

Put in End Gcode:

PRINT_END

You need to install the Klipper Setting Plugin. To do this, please follow the steps below: https://github.com/jjgraphix/KlipperSettingsPlugin Once installed, activate firmware retraction in the Klipper Settings section.

10. PrusaSlicer¶

From your printer settings, In the Start Gcode section, enter:

START_PRINT BED_TEMP=[first_layer_bed_temperature] EXTRUDER_TEMP=[first_layer_temperature]

In the End Gcode section put:

PRINT_END

In the general section of your printer settings, activate firmware retraction.

11. Calibrating your printer¶

The general calibration procedures are documented in the SmartPad calibration guides:

The steps below use the YumiOS dashboard macros, which automate the PID calibration.

12. BED PID¶

Now it's time to set the PIDs and printer settings.

Start BED PID and save the configuration: From the Dashboard, launch the BED PID 65 macro

Your tray will heat up several times to 65°C and wait 5 minutes for this to finish. Use the save macro to apply the settings on restart.

13. HOTEND PID¶

Start HOTEND PID and save the configuration: From the Dashboard, run the HOTEND 220 PID macro

Your nozzle will heat up several times to 220°C and wait 5 minutes for this to finish. Use the save macro to apply the settings on restart.

14. Print¶

I recommend starting with a calibration cube.
